It's great that you're packing reusable bags when you head to the grocery store, but what about those impulse purchases you're not expecting to make? The Temple Parachute Tote ($26) is a nearly perfect solution. Made from re-purposed WWII-era military parachutes, this rip-stop nylon bag features two large Velcro-closure inner pockets, a single, smaller interior pocket for smaller items, and collapses into a 4"x4" square when not in use, ensuring it will be with you when you need it.
